The value of the number in terms of x will be : 11x + 3

Explanation:

In the two digit number tens' digit is x and units' digit is 3 more than x , that means (x+3)

For getting a number, we will first multiply each digit by it's position and then just add all the products.

For x, the position is 10 and for (x+3), position is unit i.e. 1

So, the number will be:

[x*10]+[(x+3)*1] \\ \\ =10x + x+3\\ \\ =11x+3

Which is the equation of a line that has a slope of -2/3 ans passes through the point (-3, -1)
kupik [55]

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = - \frac{2}{3}, hence

y = - \frac{2}{3} x + c ← is the partial equation

To find c substitute (- 3, - 1) into the partial equation

- 1 = 2 + c ⇒ c = - 1 - 2 = - 3

y = - \frac{2}{3} x - 3 ← is the equation of the line

Ganezh [65]

Answer:

168 meters squared

Step-by-step explanation:

So we know that Jake walked from b to c and d meaning he didn't go from a to b, but we also know that scarlet walked a to b so to find the length we can subtract scarlet's walk by jake's walk or 38-31 which is 7.

So we know the length of one side is 7 so this means we have side a to b and c to d, but we still need to know b to c. So what we can do is get the length of a b c and d and isolate it so that we only have b to c. To do this we get the length of 7 and double it which is 14 and take it away from the 38m

38-14=24

so now we know that the side is 24 and we can solve for the area

24*7=168

so the answer is 168 meters squared
